A three-year inquiry into the death of Princess Diana and Dodi Fayed has concluded that allegations of murder were unfounded, and that there is no reason for suspecting the involvement of the royal family, a senior police officer said Thursday, Dec. 14, 2006. "Our conclusion is that, on all the evidence available at this time, there was no conspiracy to murder any of the occupants of the car. This was a tragic accident," said Lord John Stevens, former chief of the Metropolitan Police, who led the investigation of the deaths of Diana, 36, and her companion Dodi Fayed, 42. They were killed along with chauffeur Henri Paul when their Mercedes crashed in the Pont d'Alma tunnel in Paris on Aug. 31, 1997, while the couple was being chased by media photographers.

PARIS --

Admirers from around the world are paying tribute to Princess Diana at the Paris tunnel where she was killed in a car crash 15 years ago.

Tourists prayed in front of the Flame of Liberty monument to Diana above the site. Flowers, photos and messages were piled around.

British visitor Patricia Williams said Friday that Diana "became an icon. She was a very beautiful woman and things have passed on now. But Charles is now happy and I hope her sons have come to terms with it."

Princess Diana and her partner Dodi Al Fayed died when the Mercedes they were in plowed into a pillar in the Alma Tunnel on Aug. 31, 1997. French police said driver Henri Paul, who also died, had been drinking heavily and was speeding.
